Laptop with 128GB RAM support? The current Intel i7 CPUs (Sandy Bridge) support 32GB (4*8GB) and the new Intel i7 Extreme (Sandy E) support 64GB (8*8GB). So your chances are not good to hardware which supports 128GB.

Do you mean 128 GB of RAM or a 128 GB HDD/SSD? You absolutely will NOT be able to buy any laptop with 128 GB of RAM. Windows 8's Home Premium edition (or equivalent) will probably have an artificial memory limitation (hopefully higher than Windows Vista/Windows
7's 16 GB limit), but I see no reason why the Professional and Ultimate editions of Windows 8 wouldn't support 128 GB of RAM when that kind of hardware finally becomes available to consumers.

In today's market, it is absolutely impossible to find a laptop with 128 GB of RAM.

It would be a waste of time and money to try and buy a laptop for Windows 8 now.

While Microsoft may have existing or prototype models from vendors for trials, you will have to wait until Windows 8 is released and laptops are on sale with W8 installed before being sure that a laptop is hardware compatible with W8.
